The Wacom Products, BpBr duplexer in 2M (wp641) and 70CM (wp678) uses pass tuning with a series capacitor for a notch. The notch is usually set to the opposite TX or RX freq, except when there is adequate isolation and you need to notch a different offending frequency, ie, 2 repeaters sharing a single antenna system. The band reject is actually a notch on a discreet frequency and not the entire band..
